The spec requires truncation while ToUint32 originally rounded down.
This also adds a bunch of test cases to check edge case behavior.

This shows around a 2.2x speedup compared to the old JS implementation (and
3.5x compared to CPP) for the fast path.

In the shell sample don't print the result of executing a script, only
evaluating expressions.
Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
